Authorities say the man became enraged when he saw his ex-girlfriend at a west Houston nightclub and allegedly abducted her.
Investigators believe he hit her with a tire iron, ripped off her dress and threw her in a dumpster. She managed to escape in an SUV and then flagged down a deputy on the freeway feeder.
The suspect is in custody at Memorial Hermann Hospital and is being treated for a head injury. He could face several charges.
